Summary: This study evaluated the feasibility of converting 3D rotational angiography (3DRA) of congenital heart disease patients into augmented reality (AR) models and assessed physicians' perceptions of their use. The AR models showed high image quality and were helpful in identifying pathology and assisting in interventional planning. They also provided superior visualization of 3D relationships and had potential for patient/family counseling and trainee/staff education.

Summary: This study developed a real-time dose visualization system using mixed reality technology and Monte Carlo simulation for interventional radiology to reduce radiation exposure. By combining simulated patient dose distribution with fluoroscopic conditions and wearable device, the system accurately projected patient dose and user dose, while maintaining lower overall workload. The mixed reality dose visualization system shows potential in improving exposure dose management for patients and health professionals by displaying invisible radiation exposure in real space.

Summary: This paper highlights the challenges in image-guided therapies and the potential of using augmented reality to redefine surgical procedures and user interfaces. By utilizing head-mounted displays co-registered with imaging systems, new human-machine interfaces can be explored to improve surgical accuracy in procedures such as fracture management and total hip arthroplasty.

Summary: Both virtual reality (VR) and 3D printed heart models were comparable in terms of realism, with VR perceived as more useful in medical education and preoperative planning. Despite no significant difference in ratings, both VR and 3DPHM were considered to provide additional benefits compared to conventional medical imaging visualizations in the assessment of congenital heart disease (CHD). Further research involving more cardiac specialists is needed to fully assess the clinical value of these tools.

Summary: This study aimed to investigate the usefulness and clinical value of MR and 3D printing in assisting diagnosis, medical education, pre-operative planning, and intraoperative guidance of CHD surgeries through evaluations from a group of cardiac specialists and physicians. The results showed that MR models were superior to DICOM images in demonstrating complex CHD lesions and enhancing depth perception, while 3DPHM were best in facilitating communication with patients.

Summary: This paper proposes a perceptually-optimized progressive 3D streaming method for spatial quality and temporal consistency in immersive interactions. By estimating the perceptual importance based on user gaze behaviors in 2D image space and mapping it to 3D object space, the streaming priorities for edge-side rendering are scheduled.

Summary: This study proposes a novel federated learning-based viewport prediction model training algorithm that trains the model in a distributed and privacy-preserving manner using VR video viewing patterns and users' personal preferences. It also formulates a stochastic game to solve the communication resource allocation problem in VR streaming networks, and uses a deep reinforcement learning algorithm to address the lack of global information in users' data rate requesting.

Summary: This paper presents a comprehensive method for generating natural looking virtual karst caves. The method efficiently models the network and local shape of cave passages, the appearance of the wall surface, and speleothems like stalactites. It demonstrates that virtual karst caves can be generated with practical computing time and memory requirements, and can be interactively visualized and explored.

Summary: This study evaluated the manual and automatic registration times and accuracies on HoloLens 2 for aligning a 3D CT phantom model onto a CT grid. The results showed significant decrease in manual registration times on HoloLens 2, approaching those of automatic registration. The hand gesture method was significantly faster compared to Xbox controller, with no significant difference in registration accuracies. Fast, adaptive, and accurate registration is crucial for augmented reality-assisted 3D navigation during CT-guided interventions.

Summary: Dose reduction systems are beneficial for reducing patient doses, but may not be equally effective in reducing occupational doses for operators. Therefore, interventionalists should not overlook personal protection when using new technologies with dose reduction systems.

Summary: This technical note introduces an in-house phantom with a specially designed contrast-object module for three-dimensional rotational angiography (3DRA) testing. The study confirms the inadequacy of commercially available phantoms for 3D angiography, leading to the construction of a novel phantom to evaluate basic image performance metrics and vessel contrast visibility. The in-house phantom shows higher visibility in 3DRA compared to commercial phantoms and is recommended for use in 3D angiography.

Summary: Adult sized SI treatment for CoA in small patients can effectively improve gradient and minimum diameter, serving as an alternative to surgical intervention. However, SI carries risks that need to be carefully monitored for complications, and further improvements in stent technology are needed to reduce these risks.

Summary: The hemodynamic and time-related outcomes in the PAS and IDE trials were generally similar, confirming the effectiveness of the Melody TPV with real-world providers. There were few significant complications and limited power to identify important differences in adverse events. The lack of major differences in outcomes between the two studies questions the usefulness of mandated costly post-approval studies as part of the regulatory process for Class III medical devices.

Summary: This study evaluated the appropriateness of cardiovascular magnetic resonance and cardiovascular computed tomography in patients with conotruncal defects. Most studies were rated appropriate, but there was significant variation in appropriateness ratings among different centers. Younger age, CCT, and the presence of truncus arteriosus were associated with higher odds of being rated maybe or rarely appropriate.
